An unmanned Antares rocket exploded six seconds after lifting off from a private Launchpad in Wallops Island, VA on Tuesday evening. Contracted by NASA to carry approximately two tons of supplies for the International Space Station as well as “classified crypto equipment,” the rocket’s initial launch was scheduled for Monday, but was scrubbed at the last minute. RT’s Ameera David speaks to astronaut Leroy Chiao, who explains what the space agency must now do going forward.
